i'm working on a 4L60E tranny from a 97. i pulled a P1870 which is the TCC, but everyone has told me to just change the valve body, so i pulled the valve body yesterday and this is what i found.
1.- on one end of the VB
i have a 3-2 control solenoid, and on the other end is the PWM/TCC solenoid.
2.- in the middle of the two solenoids are 4 valves. the 3 closest the the PWM/TCC are spring loaded, but the one beside the 3-2 control solenoid isn't, if i push it in it stays in. so i took the one valve apart and it looks like it should be spring loaded as well the round silver that first goes out had some scoring.
3.- why cant i just change the PWM/TCC solenoid, why do i have to change the valve body as well.
the tranny has 265.000km on it but i dont have the money to replace it and i was told that if i change the valve body it will fix the problem - if it gets me through the winter i'll be happy and then in spring i'll change the tranny.
